The DeWALT® 28-Piece IMPACT READY® Accessory Set comes with the bits and holders you need to get almost any job finished quickly. This DeWalt screwdriver set is rated for use in impact drivers that generate up to 2,000 inch-pounds of torque so you can work with greater power. The black oxide coating resists rust to extend the bits' working lives. This DeWalt impact screwdriver set's bit holder allows you to work in tricky spaces. The Philips, square and slotted bits are useful in woodworking and other applications, and the socket bits are very handy on mechanical jobs. A magnetic bit holder improves retention.
